Routine varicella vaccination with one dose for children of 11 to 14 months was recommended in Germany in 2004 to reduce disease incidence and severe complications. A country-wide varicella sentinel surveillance system was initiated in 2005 to detect trends of disease frequency and vaccine uptake and to evaluate the vaccination programme. A convenient sample of about 1,000 paediatricians and ge...
In this systematic review and descriptive meta-analysis, the authors examined the post-licensure estimates of varicella vaccine effectiveness (VE) among healthy children. Publications that reported original data on dosespecific varicella VE among immunocompetent children were included. Random effects meta-analysis models were used to obtain pooled one dose VE estimates by disease severity (all ...
OBJECTIVES To evaluate the varicella immunization practices of physicians in Rochester, NY, and to identify factors that predict whether physicians administer varicella vaccine to children. DESIGN Evaluation of a 40-item survey addressing varicella immunization practices and opinions about varicella immunization that was sent to 241 pediatricians and family physicians. RESULTS A total of 17...
BACKGROUND The increasing use of varicella vaccine in children attending day care has rapidly decreased the incidence of wild-type varicella disease. The herd immunity noted is significant and will have an effect on the epidemiology of natural varicella. OBJECTIVE To monitor the change in varicella incidence in day-care attendees after the licensure of varicella vaccine. DESIGN A prospectiv...
This report presents new recommendations adopted in June 2009 by CDC's Advisory Committee on Immunization Practices (ACIP) regarding use of the combination measles, mumps, rubella, and varicella vaccine (MMRV, ProQuad, Merck & Co., Inc.). MMRV vaccine was licensed in the United States in September 2005 and may be used instead of measles, mumps, rubella vaccine (MMR, M-M-RII, Merck & Co., Inc.) ...
Varicella vaccine, a live, attenuated strain of varicella-zoster virus, was approved by the US Food and Drug Administration in March 1995. In July 1996, the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention (CDC) published its guidelines for prevention of varicella and recommended routine use of varicella vaccine for infants 12 to 18 months of age as...
BACKGROUND Little is known about the impact of the recent varicella vaccine shortage. To assess the temporal trend in varicella vaccine administration before 18 and 24 months of age in a community cohort of children prior to, during and after the recent varicella vaccine shortage. And to compare the temporal trends in varicella vaccinations to trends of an older, more widely accepted vaccine, t...
Abstract Background: Varicella is a highly contagious and dangerous disease especially in immunocompromised patients. Children with cancer are at increased risk of severe illness and may fatal cases occur. Vaccination from VZV ( varicella zoster vaccine) infection can be safe, immunogenic, and effective in children with leukemia who meet the criteria and are at the risk of serious disea...
With continuing occurrence of varicella despite increasing vaccine coverage for the past 20 years, a case-based study, a case-control study, and an immunogenicity and safety study were conducted to address the impact of varicella vaccination in South Korea. Varicella patients under the age of 16 years were enrolled for the case-based study. For the case-control study, varicella patients between...
Universal immunization of young children with 1 dose of varicella vaccine was recommended in the United States in 1995, and it has significantly decreased the incidence of chickenpox. Outbreaks of varicella, however, are reported among vaccinated children. Although vaccine effectiveness has usually been 85%, rates as low as 44% have been observed. Whether this is from primary or secondary vacci...
